ABSTRACT
OBJECTIVE: To compare the frequency of respiratory complications encountered in two different positions used for extubation i.e. conventional recovery position versus the modified recovery position (recovery position with 10-degree left tilt and head-down). STUDY DESIGN: Comparative study. Place and Duration of the Study: Department of Anaesthesia, Combine Military Hospital, Kohat, Pakistan, from April 2022 to March 2023. METHODOLOGY: Two hundred patients scheduled for elective nose and throat surgeries were equally divided into two groups (Group C and Group M). Patients with history of bronchial asthma, chronic obstructive pulmonary disease (COPD), recent respiratory infection, and gastro-oesophageal reflux disease (GERD) were excluded from this study. Patients with more than two intubation attempts were also excluded. Group C patients were extubated in a conventional left lateral recovery position, whereas Group M patients were extubated in a modified recovery position with patient in a left lateral position with 10-degree head-down and 10-degree left tilt. All patients were observed for persistent coughing (coughing that lasted for at least 2 minutes after extubation), breath holding for 20 seconds or more, desaturation (oxygen saturation less than 90%), laryngospasm, need for reintubation, vomiting, and regurgitation. RESULTS: Frequency of airway complications was significantly higher in Group C as compared to Group M. In Group C, 18 (18%) out of hundred patients had complications compared to 6 (6%) patients only in Group M (p = 0.009). CONCLUSION: Extubation in a modified recovery position is associated with reduced frequency of airway complications as compared to the conventional recovery position. KEY WORDS: Airway complications, Extubation, Cough, Laryngospasm, Recovery position.

BACKGROUND: Trunk inclination in patients with Acute Respiratory Distress Syndrome (ARDS) in the supine position has gained scientific interest due to its effects on respiratory physiology, including mechanics, oxygenation, ventilation distribution, and efficiency. Changing from flat supine to semi-recumbent increases driving pressure due to decreased respiratory system compliance. Positional adjustments also deteriorate ventilatory efficiency for CO2 removal, particularly in COVID-19-associated ARDS (C-ARDS), indicating likely lung parenchyma overdistension. Tilting the trunk reduces chest wall compliance and, to a lesser extent, lung compliance and transpulmonary driving pressure, with significant hemodynamic and gas exchange implications. METHODS: A prospective, pilot physiological study was conducted on early ARDS patients in two ICUs at CHU Clermont-Ferrand, France. The protocol involved 30-min step gradual verticalization from a 30° semi-seated position (baseline) to different levels of inclination (0°, 30°, 60°, and 90°), before returning to the baseline position. Measurements included tidal volume, positive end-expiratory pressure (PEEP), esophageal pressures, and pulmonary artery catheter data. The primary endpoint was the variation in transpulmonary driving pressure through the verticalization procedure. RESULTS: From May 2020 through January 2021, 30 patients were included. Transpulmonary driving pressure increased slightly from baseline (median and interquartile range [IQR], 9 [5-11] cmH2O) to the 90° position (10 [7-14] cmH2O; P < 10-2 for the overall effect of position in mixed model). End-expiratory lung volume increased with verticalization, in parallel to decreases in alveolar strain and increased arterial oxygenation. Verticalization was associated with decreased cardiac output and stroke volume, and increased norepinephrine doses and serum lactate levels, prompting interruption of the procedure in two patients. There were no other adverse events such as falls or equipment accidental removals. CONCLUSIONS: Verticalization to 90° is feasible in ARDS patients, improving EELV and oxygenation up to 30°, likely due to alveolar recruitment and blood flow redistribution. However, there is a risk of overdistension and hemodynamic instability beyond 30°, necessitating individualized bed angles based on clinical situations.

PURPOSE: Awake prone positioning has been reported to reduce endotracheal intubation in patients with coronavirus disease 2019 (COVID-19)-related acute hypoxemic respiratory failure (AHRF). However, it is still unclear whether using the awake prone positioning for longer periods can further improve outcomes. METHODS: In this randomized, open-label clinical trial conducted at 12 hospitals in China, non-intubated patients with COVID-19-related AHRF were randomly assigned to prolonged awake prone positioning (target > 12 h daily for 7 days) or standard care with a shorter period of awake prone positioning. The primary outcome was endotracheal intubation within 28 days after randomization. The key secondary outcomes included mortality and adverse events. RESULTS: In total, 409 patients were enrolled and randomly assigned to prolonged awake prone positioning (n = 205) or standard care (n = 204). In the first 7 days after randomization, the median duration of prone positioning was 12 h/d (interquartile range [IQR] 12-14 h/d) in the prolonged awake prone positioning group vs. 5 h/d (IQR 2-8 h/d) in the standard care group. In the intention-to-treat analysis, intubation occurred in 35 (17%) patients assigned to prolonged awake prone positioning and in 56 (27%) patients assigned to standard care (relative risk 0.62 [95% confidence interval (CI) 0.42-0.9]). The hazard ratio (HR) for intubation was 0.56 (0.37-0.86), and for mortality was 0.63 (0.42-0.96) for prolonged awake prone positioning versus standard care, within 28 days. The incidence of pre-specified adverse events was low and similar in both groups. CONCLUSION: Prolonged awake prone positioning of patients with COVID-19-related AHRF reduces the intubation rate without significant harm. These results support prolonged awake prone positioning of patients with COVID-19-related AHRF.

BACKGROUND: At present, the guidelines for urology recommend percutaneous nephrolithotomy (PCNL) as the preferred treatment for staghorn renal calculi (SRC). However, for complete SRC, it has been questioned by clinicians and patients due to high residual stone rate, complications, repeated hospitalizations and high treatment cost. Anatrophic nephrolithotomy (ANL) is a traditional and classic method for the treatment of SRC. Due to its high trauma and high technical requirements, it is difficult to carry out in primary hospitals, and gradually replaced by PCNL. The purpose of this study is to compare the efficacy of PCNL and ANL in the treatment of complete SRC. METHODS: Overall, 238 patients with complete SRC were divided into mini-PCNL in lateral supine position group, (n = 190) and ANL group (n = 94) according to treatment for a retrospective cohort study. The calculi parameters, renal function index, comorbidities of calculi, surgical complications, length and frequency of hospitalization, treatment costs, results of postoperative satisfaction survey were compared between the two groups. RESULTS: The risk of the residual stone rate after mini-PCNL in lateral supine position was 239 times (OR = 238.667, P < 0.0001), the number of residual stone 1.3 times (OR = 1.326, P < 0.0001), the amount of residual stone 2.2 times (OR = 2.224, P < 0.0001) that of ANL. The risk of the cost of initial treatment after mini-PCNL in lateral supine position was 3.3 times (OR = 3.273, P < 0.0001), the total cost of treatment 4 times (OR = 4.051, P < 0.0001), the total length of hospital stays 1.4 times (OR = 1.44, P < 0.0001) that of ANL, the incidence of postoperative renal atrophy was 2.2 times (OR = 2.171, P = 0.008) higher in the ANL than in the mini-PCNL in lateral supine position. Glomerular filtration rate (GFR) reduction after ANL was 1.4 times (OR = 1.381, P = 0.037) greater than that after mini-PCNL in lateral supine position at 24-month follow-up. The risk of the overall satisfaction of ANL was 58 times (OR = 57.857, P < 0.0001) higher than that of mini-PCNL in lateral supine position, the number of branches of staghorn greater than 8 is a high risk factor for the occurrence of residual stone after mini-PCNL in lateral supine position (OR = 353.137, P < 0.0001). CONCLUSION: Although the risk of renal atrophy and decreased GFR after ANL is higher than that of mini-PCNL in lateral supine position, the efficacy of traditional ANL in the treatment of complete SRC was generally superior to that of mini-PCNL in lateral supine position. Moreover, number of branches of staghorn greater than 8 are the preferred ANL for complete SRC. TRIAL REGISTRATION: ChiCTR2100047462.

<b>Introduction:</b> The main cause of groin pain is inguinal hernia (IH). The most commonly used imaging test for diagnosis is sonography, which is also useful in distinguishing between indirect and direct hernias.<b>Aim:</b> In this study, measurements were made with sonography in the semi-erect position (45) in addition to the supine position and the effectiveness of this position in detecting the defect was investigated.<b>Material and methods:</b> The IH cases diagnosed by ultrasound between March 2019 and October 2023 were evaluated retrospectively. According to the diameter of the defect in the supine position, the cases were divided into three groups: Group A (≤1.5 cm), Group B (1.5-3 cm), and Group C (≥3 cm). A total of 252 patients with unilateral IH were identified.<b>Results:</b> For Group A, the mean value was 1.09 0.23 (0.64-1.48) cm in the supine position and 1.28 0.26 (0.67) cm in the semi- -erect position (p<0.001). For Group B, the mean value was 2.29 0.29 (1.57-2.82) cm in the supine position and 2.41 0.31 (1.65-2.94) cm in the semi-erect position (p<0.001). For Group C, the mean value was 3.57 0.23 (3.28-4.05) cm in the supine position and 3.62 0.24 (3.32-4.10) cm in the semi-erect position (p<0.05).<b>Conclusions:</b> Superficial ultrasound, which provides reliable results in the diagnosis of IH, is an easily accessible modality. Unlike previous studies, this study was the first to examine the semi-erect position in IH patients. It showed that it is effective in determining the optimal diameter of the defect.

To evaluate whether different positions are advantageous for hemodynamics and respiratory balance in patients undergoing percutaneous nephrolithotomy (PCNL) procedures. Pre- and postoperative arterial blood gas data obtained during spontaneous breathing for 67 prone (Group 1) and 56 supine (Group 2) patients undergoing PCNL were analyzed. Additionally data on all patients' gender, age, body mass index, stone size, access and surgical duration, volume of irrigation fluid, length of hospital stay, requirement for blood transfusion, and residual stones were recorded: There were no differences between the groups in terms of age, stone size, operation time, access time, radiation exposure, transfusion requirements, stone-free rate, and length of hospitalization. A statistically significant pH decrease was observed in both groups in the postoperative period (p = 0.001 and p = 0.001, respectively). There was a statistically significant increase in pCO2 values in both groups in the postoperative period (p = 0.001 and p = 0.024, respectively), and that increase did not differ significantly between the groups (p = 0.624). A statistically significant decrease in pO2 and SpO2 values was observed in both groups in the postoperative period compared to the preoperative period. Again, no statistical difference was observed between the groups for these values. There was a statistically significant decrease in bicarbonate in both groups period (p < 0.001 and p = 0.001, respectively). Hemodynamics and the respiratory balance of the patient are impaired in both prone and supine positions. Neither position is superior to the other in this respect.

The current S3 guideline, "Positioning Therapy and Mobilization of Critically Ill Patients in Intensive Care Units", introduces methodological changes and substantive updates compared to the previous version. Additionally, new evidence-based insights with specified PICO questions have been integrated, aiming for a more precise application of recommendations in clinical practice and thus enhancing the care of critically ill patients.A notable aspect is the more nuanced approach to early mobilization, which is recommended to commence within the first 72 hours of ICU admission. A staged concept and score-based mobilization schema facilitate improved patient rehabilitation. Mobilization should be standard of care, i.e., immobilization should be ordered by the physician. The guideline provides suggestions for the duration and additional mobilization measures to ensure patients stand, transfer actively from bed to chair, or walk as frequently as possible. These recommendations apply even during ECMO therapy, highlighting the importance of early mobilization.Further updates include semi-recumbent positions of at least 40° in intubated patients, with careful consideration of potential side effects. Continuous lateral rotation therapy (CLRT) is not advised due to the progress in intensive care therapy, shifting from deep sedation toward responsive patient management.Prone positioning (PP) involves rotating the patient 180° onto the ventral side. It is recommended as a therapeutic option for invasively ventilated patients with ARDS and impaired arterial oxygenation (PaO2/FiO2 <150mmHg), with a recommended minimum duration of 12 hours, ideally 16 hours. Special recommendations apply, for example, to COVID-19 patients with acute hypoxemic respiratory failure, where awake proning should be considered.Additionally, new chapters have been introduced focusing on assistive devices and neuromuscular electrical stimulation.

OBJECTIVES: To identify factors that contribute to iatrogenic sciatic nerve palsy during acetabular surgery through a Kocher-Langenbeck approach and to evaluate if variation among individual surgeons exists. DESIGN: Retrospective cohort. SETTING: Level I trauma center. PATIENT SELECTION CRITERIA: Adults undergoing fixation of acetabular fractures (AO/OTA 62) through a posterior approach by 9 orthopaedic traumatologists between November 2010 and November 2022. OUTCOME MEASURES AND COMPARISONS: The prevalence of iatrogenic sciatic nerve palsy and comparison of the prevalence and risk of palsy between prone and lateral positions before and after adjusting for individual surgeon and the presence of transverse fracture patterns in logistic regression. Comparison of the prevalence of palsy between high-volume (>1 patient/month) and low-volume surgeons. RESULTS: A total of 644 acetabular fractures repaired through a posterior approach were included (median age 39 years, 72% male). Twenty of 644 surgeries (3.1%) resulted in iatrogenic sciatic nerve palsy with no significant difference between the prone (3.1%, 95% confidence interval [CI], 1.9%-4.9%) and lateral (3.3%, 95% CI, 1.3%-8.1%) positions (P = 0.64). Logistic regression adjusting for surgeon and transverse fracture pattern demonstrated no significant effect for positions (odds ratio 1.0, 95% CI, 0.3-3.9). Transverse fracture pattern was associated with increased palsy risk (odds ratio 3.0, 95% CI, 1.1-7.9). Individual surgeon was significantly associated with iatrogenic palsy (P < 0.02). CONCLUSIONS: Surgeon and the presence of a transverse fracture line predicted iatrogenic nerve palsy after a posterior approach to the acetabulum in this single-center cohort. Surgeons should perform the Kocher-Langenbeck approach for acetabular fixation in the position they deem most appropriate, as the position was not associated with the rate of iatrogenic palsy in this series. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE: Medical adhesive-related skin injuries (MARSI), defined as skin damage associated with the use of medical adhesive products or devices, are a common and under-reported condition that compromises skin integrity. The prevention and management of MARSI that can occur around the needle insertion site of a chest wall implantable port in hospitalised patients with a tumour remain challenging issues. The aim of this study was to explore whether the incidence of MARSI could be reduced by changing the body position during dressing changes. METHOD: Participants were recruited between May 2019 and November 2020 in the oncology department of a tertiary hospital. Patients were randomly assigned to Group AB (supine followed by semi-recumbent position) and Group BA (semi-recumbent followed by supine position) with a standard intervening recovery interval of 21-28 days. Assessments for typical MARSI included itching, the combination of erythema and oedema, and blisters in the port area, and were graded according to the level of severity. RESULTS: The itch intensity was significantly lower in phase B (semi-recumbent) compared to phase A (supine) (2.35±1.985 versus 5.31±1.332, respectively; p<0.01). Similarly, the severity of erythema and oedema was less severe when comparing phase B to phase A: grade 0 (64.9% versus 10.5%, respectively); grade 1 (28.1% versus 19.3%, respectively); grade 2 (3.5% versus 7.0%, respectively); grade 3 (1.8% versus 45.6%, respectively); and grade 4 (1.8% versus 17.5%, respectively) (Z=5.703; p<0.01). Blisters were found far less frequently in phase B than phase A (1.8% versus 56.1%, respectively; p<0.01). CONCLUSION: The study provided statistically significant evidence that patients in a semi-recumbent position receiving dressing at a chest wall implantable port had fewer and less severe injection site MARSI than when in a supine position. DECLARATION OF INTEREST: The authors have no conflicts of interest to declare.

BACKGROUND: This study aimed to evaluate the accuracy of ankle blood pressure measurements in relation to invasive blood pressure in the lateral position. METHODS: This prospective observational study included adult patients scheduled for elective non-cardiac surgery under general anesthesia in the lateral position. Paired radial artery invasive and ankle noninvasive blood pressure readings were recorded in the lateral position using GE Carescape B650 monitor. The primary outcome was the ability of ankle mean arterial pressure (MAP) to detect hypotension (MAP < 70 mmHg) using area under the receiver operating characteristic curve (AUC) analysis. The secondary outcomes were the ability of ankle systolic blood pressure (SBP) to detect hypertension (SBP > 140 mmHg) as well as bias (invasive measurement - noninvasive measurement), and agreement between the two methods using the Bland-Altman analysis. RESULTS: We analyzed 415 paired readings from 30 patients. The AUC (95% confidence interval [CI]) of ankle MAP for detecting hypotension was 0.88 (0.83-0.93). An ankle MAP of ≤ 86 mmHg had negative and positive predictive values (95% CI) of 99 (97-100)% and 21 (15-29)%, respectively, for detecting hypotension. The AUC (95% CI) of ankle SBP to detect hypertension was 0.83 (0.79-0.86) with negative and positive predictive values (95% CI) of 95 (92-97)% and 36 (26-46)%, respectively, at a cutoff value of > 144 mmHg. The mean bias between the two methods was - 12 ± 17, 3 ± 12, and - 1 ± 11 mmHg for the SBP, diastolic blood pressure, and MAP, respectively. CONCLUSION: In patients under general anesthesia in the lateral position, ankle blood pressure measurements are not interchangeable with the corresponding invasive measurements. However, an ankle MAP > 86 mmHg can exclude hypotension with 99% accuracy, and an ankle SBP < 144 mmHg can exclude hypertension with 95% accuracy.

BACKGROUND: Adjusting trunk inclination from a semi-recumbent position to a supine-flat position or vice versa in patients with respiratory failure significantly affects numerous aspects of respiratory physiology including respiratory mechanics, oxygenation, end-expiratory lung volume, and ventilatory efficiency. Despite these observed effects, the current clinical evidence regarding this positioning manoeuvre is limited. This study undertakes a scoping review of patients with respiratory failure undergoing mechanical ventilation to assess the effect of trunk inclination on physiological lung parameters. METHODS: The PubMed, Cochrane, and Scopus databases were systematically searched from 2003 to 2023. INTERVENTIONS: Changes in trunk inclination. MEASUREMENTS: Four domains were evaluated in this study: 1) respiratory mechanics, 2) ventilation distribution, 3) oxygenation, and 4) ventilatory efficiency. RESULTS: After searching the three databases and removing duplicates, 220 studies were screened. Of these, 37 were assessed in detail, and 13 were included in the final analysis, comprising 274 patients. All selected studies were experimental, and assessed respiratory mechanics, ventilation distribution, oxygenation, and ventilatory efficiency, primarily within 60 min post postural change. CONCLUSION: In patients with acute respiratory failure, transitioning from a supine to a semi-recumbent position leads to decreased respiratory system compliance and increased airway driving pressure. Additionally, C-ARDS patients experienced an improvement in ventilatory efficiency, which resulted in lower PaCO2 levels. Improvements in oxygenation were observed in a few patients and only in those who exhibited an increase in EELV upon moving to a semi-recumbent position. Therefore, the trunk inclination angle must be accurately reported in patients with respiratory failure under mechanical ventilation.

BACKGROUND: During laparoscopic surgery, pneumoperitoneum and Trendelenburg positioning applied to provide better surgical vision can cause many physiological changes as well as an increase in intracranial pressure. However, it has been reported that cerebral autoregulation prevents cerebral edema by regulating this pressure increase. This study aimed to investigate whether the duration of the Trendelenburg position had an effect on the increase in intracranial pressure using ultrasonographic optic nerve sheath diameter (ONSD) measurements. METHODS: The near infrared spectrometry monitoring of patients undergoing laparoscopic hysterectomy was performed while awake (T0); at the fifth minute after intubation (T1); at the 30th minute (T2), 60th minute (T3), 75th minute (T4), and 90th minute (T5) after placement in the Trendelenburg position; and at the fifth minute after placement in the neutral position (T6). RESULTS: The study included 25 patients. The measured ONSD values were as follows: T0 right/left, 4.18±0.32/4.18±0.33; T1, 4.75±0.26/4.75±0.25; T2, 5.08±0.19/5.08±0.19; T3, 5.26±0.15/5.26±0.15; T4, 5.36±0.11/5.37±0.12; T5, 5.45±0.09/5.48±0.11; and T6, 4.9±0.24/4.89±0.22 ( p < 0.05 compared with T0). ). No statistical difference was detected in all measurements in terms of MAP, HR and ETCO2 values compared to the T0 value (p > 0.05). CONCLUSIONS: It was determined that as the Trendelenburg position duration increased, the ONSD values ââincreased. This suggests that as the duration of Trendelenburg positioning and pneumoperitoneum increases, the sustainability of the mechanisms that balance the increase in intracranial pressure becomes insufficient.

PURPOSE: The purpose of this quality improvement (QI) project was to develop and implement repositioning guidelines that reduce pressure injury (PI) in hemodynamically unstable pediatric intensive care unit (PICU) patients. PARTICIPANTS AND SETTING: All PICU patient ages 0 to 36 months who required sedation for invasive mechanical ventilation and had a Braden Q score ≤ 18 were eligible for inclusion. The project was implemented in 116 patients preimplementation and 100 postimplementation. Their median t age was 5 months (interquartile range 2-13 months). The QI project setting was an academic hospital PICU with a Level I trauma center located in the Mid-Atlantic Region of the United States. APPROACH: A pre-post observational design was used to compare the at-risk population for 21 weeks before (August-December 2018) and after (August-December 2019) implementing repositioning guidelines. Turn attempts were undertaken every 2 hours. Repositioning attempts were defined as (1) full (30°); (2) partial (15°); (3) unable to turn owing to hemodynamic instability; or (4) noncompliance. The primary outcome was incidence of Stage II or higher PI. OUTCOMES: We found a significant reduction in the incidence of PI before and after implementation of the repositioning intervention (16.4% vs 2.0%, P = .0003). IMPLICATIONS FOR PRACTICE: A structured intervention for repositioning hemodynamically unstable PICU patients has the potential to significantly lower PI incidence in a group of hemodynamically unstable children.

BACKGROUND: For patients receiving one lung ventilation in thoracic surgery, numerous studies have proved the superiority of lung protective ventilation of low tidal volume combined with recruitment maneuvers (RM) and individualized PEEP. However, RM may lead to overinflation which aggravates lung injury and intrapulmonary shunt. According to CT results, atelectasis usually forms in gravity dependent lung regions, regardless of body position. So, during anesthesia induction in supine position, atelectasis usually forms in the dorsal parts of lungs, however, when patients are turned into lateral decubitus position, collapsed lung tissue in the dorsal parts would reexpand, while atelectasis would slowly reappear in the lower flank of the lung. We hypothesize that applying sufficient PEEP without RM before the formation of atelectasis in the lower flank of the lung may beas effective to prevent atelectasis and thus improve oxygenation as applying PEEP with RM. METHODS: A total of 84 patients scheduled for elective pulmonary lobe resection necessitating one lung ventilation will be recruited and randomized totwo parallel groups. For all patients, one lung ventilation is initiated the right after patients are turned into lateral decubitus position. For patients in the study group, individualized PEEP titration is started the moment one lung ventilation is started, while patients in the control group will receive a recruitment maneuver followed by individualized PEEP titration after initiation of one lung ventilation. The primary endpoint will be oxygenation index measured at T4. Secondary endpoints will include intrapulmonary shunt, respiratory mechanics, PPCs, and hemodynamic indicators. DISCUSSION: Numerous previous studies compared the effects of individualized PEEP applied alone with that applied in combination with RM on oxygenation index, PPCs, intrapulmonary shunt and respiratory mechanics after atelectasis was formed in patients receiving one lung ventilation during thoracoscopic surgery. In this study, we will apply individualized PEEP before the formation of atelectasis while not performing RM in patients allocated to the study group, and then we're going to observe its effects on the aspects mentioned above. The results of this trial will provide a ventilation strategy that may be conductive to improving intraoperative oxygenation and avoiding the detrimental effects of RM for patients receiving one lung ventilation.

Objective: This article presents a literature review to explore and analyze the current situation of pressure ulcers or lesions or decubitus ulcers, pathophysiological, epidemiological aspects, and risk factors. The progress in evidence of the effectiveness of preventive repositioning in the appearance of these lesions in vulnerable hospitalized patients is also evaluated. Methods: Databases were reviewed in non-systematic manner, including the Cochrane Wounds Specialized Register; Medline, Scopus, PubMed, the Cochrane Central Register of Controlled Trials; MEDLINE (Ovid); EMBASE (Ovid), Web of Science, SciELO, and Lilacs. The general search terms included [pressure ulcers or pressure lesions or decubitus ulcers] and [prevention or preventive] and [repositioning or positioning or position changes or postural change] and [patient at risk or vulnerable] and [hospitalized or ICU or intensive care]. Systematic literature reviews, randomized clinical trials, observational studies, cost-effectiveness and qualitative studies in English or Spanish were included. Results: Although globally, the incidence, prevalence, and years of disability associated to these lesions has diminished between 1990 and 2019, the high impact on health persists. Evidence found on the effectiveness of repositioning in preventing pressure ulcers and health associated costs has been evaluated with certainty between low and very low, as a result of conducting research with serious methodological limitations that report results with high inaccuracy. Conclusion: The findings reported present that these lesions persist at hospital level and continue being a global social and health problem with high impact on health budgets. Likewise, there is a need to develop greater quality research on prevention strategies, such as repositioning, which validate their effectiveness, and justify their use.

BACKGROUND: Many patients critically ill with COVID-19 develop acute respiratory distress syndrome (ARDS) necessitating mechanical ventilation and proning. Although proning is lifesaving, it has been linked to the occurrence of facial pressure injuries (PIs). OBJECTIVES: To evaluate the incidence and use of prevention strategies and identify predictors of facial PIs in patients who received ventilator and proning treatments in COVID-designated intensive care units at 2 large quaternary medical centers in the Midwest. METHOD: This was a retrospective cohort study using data extracted from an electronic health record between October 2020 and February 2022. Demographics, clinical and care variables, and PI outcomes were analyzed to identify predictors of PI using logistic and Cox regression. RESULTS: The cohort (N = 150) included patients from 2 units, unit a (n = 97) and unit b (n = 53) with a mean age of 60 years, with 68% identifying as male. Patients were vented for an average of 18 (SD, 16.2) days and proned for an average of 3 (SD, 2.5) days. Many (71%) died. Over half (56%) developed facial PI with a proning-exposure-adjusted incidence rate of 18.5%. Patients with PI were significantly different in several factors. Logistic regression showed predictors of PIs were duration of mechanical ventilation (in days; P = .02) and head turned (P = .01). Cox regression also identified head turn as predictive (P < .01), with Black/African American race as protective (P = .03). DISCUSSION: Critically ill patients with COVID-19 receiving ventilator and proning therapy developed facial PIs despite the use of recommended prevention practices. Further research on effective PI prevention strategies is needed.

OBJECTIVE: Extra-articular open fractures of the leg often result from high energy trauma. After healing, a painful ankle impingement may occur. In the event of anterior and posterior impingements, arthroscopic treatment may require two surgical positions. We propose an operative strategy to treat anterior and posterior ankle impingement after extra-articular open fracture of the leg. Our hypothesis is that this strategy is simple, effective and with a low risk of complication. MATERIAL AND METHOD: Anterior ankle impingements were treated by anterior arthroscopy in supine position; anterior and posterior impingements were treated by anterior and posterior arthroscopy in supine position; anterior and posterior impingements associated with retraction of gastrocnemius muscles were treated with anterior arthroscopy in supine position followed by posterior arthroscopy in prone position, and an open tendon lengthening of the calcaneal tendon in the same position. The anterior and posterior arthroscopic release was tested in the cadaver laboratory. Then, the surgical strategy was applied to our patients in our clinical practice. After, we analysed retrospectively the results of the strategy in the first patients treated for a painful ankle impingement after extra-articular open fracture of the leg. The data retrieved were the importance of pain (VAS), the presence of clinical instability, ankle mobility, gastrocnemius retraction and the AOFAS functional score and the post-operative complications. Then, these data were compared before the surgery and at last follow-up. RESULTS: From the cadaver laboratory, anterior and posterior arthroscopic release was possible in all cases without changing position. From our clinical practice, we included 5 patients (3 women and 2 men, mean age 43 years) suffering from an ankle impingement after extra-articular open fracture of the leg (2 patients with isolated anterior impingement, 1 patient with anterior and posterior impingement, and 2 patients with anterior and posterior impingement plus a gastrocnemius retraction). All post-operative parameters (pain, range of motion and AOFAS score) at mean follow-up of 53 months were improved. No post-operative complication was reported. CONCLUSION: We propose a surgical strategy adapted to the different clinical presentations of ankle impingement after extra-articular open fracture of the leg.
